SN74LS48DR from lingxingic, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Data input B of the BCD code. |
| 2 | C | input | Data input C of the BCD code. |
| 3 | LT | input | Active-low lamp test input; with BI/RBO open or high, a low on LT turns all segment outputs on. |
| 4 | BI/RBO | bidirectional | Active-low blanking input/ripple blanking output; a low on BI forces all segment outputs off, and it must be open or high for outputs 0 through 15. |
| 5 | RBI | input | Active-low ripple blanking input; must be open or high if blanking of a decimal zero is not desired. |
| 6 | D | input | Data input D of the BCD code. |
| 7 | A | input | Data input A of the BCD code. |
| 8 | GND | power_in | Ground (0V). |
| 9 | e | output | Segment e data output, active low. |
| 10 | d | output | Segment d data output, active low. |
| 11 | c | output | Segment c data output, active low. |
| 12 | b | output | Segment b data output, active low. |
| 13 | a | output | Segment a data output, active low. |
| 14 | g | output | Segment g data output, active low. |
| 15 | f | output | Segment f data output, active low. |
| 16 | VCC | power_in | Supply voltage, recommended 2.0V to 6.0V (absolute maximum 7.0V). |
